There is an association between the development of an idiopathic hydrocele and testicular size and vascular resistance. We believe that the increase in volume and vascular resistance is due to an increase in impedance to venous and lymphatic flow.
In this study, lipid peroxide and total sulfhydryl contents and activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were investigated in the plasma of patients with benign prostatic hyperplasia (BPH) and prostate cancer. No significant change was found in lipid peroxidation or antioxidant systems in the plasma of patients with BPH and prostate cancer. The results indicate that evaluation of the prooxidant-antioxidant balance in the plasma of BPH and prostate cancer patients cannot be used as a marker to discriminate between these diseases.
In this prospective study the incidence of gynecomastia was not as high as previously believed. Although prophylactic breast irradiation seemed to decrease the gynecomastia rate in patients on 150 mg bicalutamide, our study proves that not all patients need prophylaxis since only 52% were significantly bothered by gynecomastia. Thus, individual assessment is needed to select patients who need prophylactic radiation while on 150 mg bicalutamide.
A rare case of malignant Leydig cell tumour of the testis is presented. There was no standard therapy regimen. Leydig cell carcinoma is relatively refractory to radiotherapy and chemotherapy. So a retroperitoneal node dissection should be performed before or after chemotherapy for staging and also for therapeutic reasons.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
